西藏自然环境条件特殊,生态环境脆弱。随城市化和旅游业快速发展,生活垃圾/污泥产量急增。目前,生活垃圾/污泥仍以填埋为主,焚烧处于试运行,总体上缺乏先进的处置技术。本研究分析了西藏垃圾/污泥的特点;利用层燃焚烧炉分析了西藏和天津垃圾/污泥在焚烧过程中的差异,探讨了西藏垃圾和污泥在不同混合比下的焚烧特性。初步确定了西藏污泥与垃圾混合焚烧的最佳掺混比为4∶1,CO排放降低达23.06%,HCl降低达45.51%,颗粒物浓度降低约30.73%。考虑到西藏生态环境的不可逆转性及其作为国家生态安全屏障的战略性,本研究为其固废混合焚烧处理过程的污染物控制提供了指导,为混合焚烧处理的工程化应用提供参考。
Tibet Autonomous Region has special geographical conditions and a fragile ecological environment. The yield of Tibetan municipal solid waste (MSW) and sewage sludge (SS) has been increasing rapidly due to the development of urbanization and tourism. At present
the main treatment method of MSW/SS is landfill
while incineration is still at trial operation stage
and generally lack of advanced disposal technology. In this study
the characteristics of MSW and SS in the Tibet were investigated. The differences during the incineration process between wastes from Tibet and Tianjin were analyzed in a grate furnace. Also
the incineration characteristics of Tibetan MSW and SS under different mixing ratios was studied. The optimum blending ratio was preliminarily determined to be 4∶1 which reduced the emissions of CO by 23.06%
HCl by 45.51%
and PM by 30.73%. Considering the irreversibility of the ecological environment in Tibet and its strategic role as a national ecological safety barrier
this study provides guidance for pollutant control in the waste incineration process and reference for the engineering application of MSW and SS co-incineration in Tibet.
